The effect of plasma profile variation on the stability of the n=1 internal kink mode in rotating tokamak plasmas

The sensitivity of the stability of the ideal n = 1 internal kink mode to variations in the plasma profiles is analysed both analytically and numerically in rotating tokamak plasmas. These stability analyses have been carried out including the centrifugal ...

Experimental demonstration of an up-down asymmetry effect on intrinsic rotation in the TCV tokamak

Olivier Sauter, Basil Duval, Alexander Karpushov, Yann Camenen, Alessandro Bortolon, Lucia Isabel Federspiel, Francesco Piras

A new mechanism has recently been proposed that generates a radial flux of parallel momentum in toroidal plasmas. Namely, by considering up-down asymmetric flux surfaces, the symmetry following the magnetic field can be broken and an additional contributio ...

Hydrogen Dynamics in Lightweight Tetrahydroborates

The high hydrogen content in complex hydrides such as M[AIH 4]x and M[BH4]x (M = Li, Na, K, Mg, Ca) stimulated many research activities to utilize them as hydrogen storage materials. An understanding of the dynamical properties on the molecular level is im ...

Automatic Gait Generation in Modular Robots: to Oscillate or to Rotate? that is the question

Auke Ijspeert, Alexander Spröwitz, Soha Pouya, Jesse van den Kieboom

Modular robots offer the possibility to design robots with a high diversity of shapes and functionalities. This nice feature also brings an important challenge: namely how to design efficient locomotion gaits for arbitrary robot structures with many degree ...

Analysis of Multiview Omnidirectional Images in a Spherical Framework

Zafer Arican

With the increasing demand of information for more immersive applications such as Google Street view or 3D movies, the efficient analysis of visual data from cameras has gained more importance. This visual information permits to extract some crucial inform ...

Non-Rigid Consistent Registration of 2D Image Sequences

Philippe Thévenaz

We present a novel algorithm for the registration of 2D image sequences that combines the principles of multiresolution B-spline-based elastic registration and those of bidirectional consistent registration. In our method, consecutive triples of images are ...

Complete H-1 resonance assignment of beta-maltose from H-1-H-1 DQ-SQ CRAMPS and H-1 (DQ-DUMBO)-C-13 SQ refocused INEPT 2D solid-state NMR spectra and first principles GIPAW calculations

David Lyndon Emsley

A disaccharide is a challenging case for high-resolution H-1 solid-state NMR because of the 24 distinct protons (14 aliphatic and 10 OH) having H-1 chemical shifts that all fall within a narrow range of approximately 3 to 7 ppm. High-resolution H-1 (500 MH ...

The mechanisms of the fcc-bcc martensitic transformation revealed by pole figures

Cyril Cayron

Face-centered cubic (fcc) to body-centered cubic (bcc) martensitic transformations occur in many materials, such as steels, FeNi meteorites or brass. The phenomenological theory has been the accepted theory for these transformations for more than half a ce ...

Camera Orientation Based on Matching Road Networks

The following paper shows an approach to measure orientation data of sensors during an airplane flight for traffic data acquisition. This orientation data is necessary for georegistration of any taken aerial images and extracted features. Since an inertial ...

Optical tomography with digital holographic microscopy

Christian Depeursinge, Nicolas Pavillon, Florian Charrière

Three-dimensional optical imaging by tomographic techniques is presented, especially with object rotation in a transmission configuration. In digital holographic microscopy, the complex field is measured, which permits either to study transparent objects w ...
